One of my friends made the mistake of linking his PSN account right when he started playing Helldivers 2 then shortly found he was banned from the game. After he did some digging, he found his PSN account was banned for "suspicious activities" despite having not used it in over a year. After even more digging he eventually finds out it was because when they kept charging him for their premium service and he was trying to cancel it, they wouldn't remove his payment information. He checked multiple times with them and they said they did.

Next payment period rolls around and they charge him for another year of service all the same. He tries to get it refunded, he talks to them about how they said they removed the payment info and it's nothing but "well there's nothing we can do about it now" type bullshit. So he goes to his bank and did a charge back on the annual fee, since they keep insisting it's impossible. Wouldn't ya know it suddenly it's very easy to remove his payment info, cancel that premium service, and take care of everything.

All of this was done about a year prior, and he left his account untouched since fuck Sony and PlayStation at that point. I guess they waited until his account was active again being used for a game for them to suddenly realize they really don't like his charge back and deactivate his account entirely, blocking access to everything linked to it, including Helldivers 2.
